EHCLE-"WHEEL 1,168,333, Speel-.cation of Letters Be it knou'n 'that I, {li-lonen Balans, a resident ci? lilcleesport, in the county ot Allegheny and State or' Pennsylrania, have inrented a new and useinl lmproreinent in Yehicle-ll'heels, ot which the following is a specification.

'l`his invention relates to an iinpr'einen in Vehicle Wheels, and particularly in wire spoke wheels for automobiles and the like.

The object of the invention is to produce an improved vehicle wheelv which is readily delnountable from the axle, which may be tted to any arrangement of axle end. whose hub is straight or cylindrical with an un broken surface, thereby presenting' a goed appearance, and wherein thereare no hooks or crannies for the lodginen-t of inud and Water, whereby it is unnecessary to deinount the Wheel for cleaning and there is no liability of the demountable parts rustingv fastto the inner or lixed hub member.

A further object o" the invention is to' provide a Wheel embodying` inner and outer hub members with clamping means for the outer hub member arranged so that the clamping strain is in line with and counteracts the strain of the spokes on the hub and wherein the end portions of the outer hub member are covered and reinforced by the clamping parts.

, The invention comprises the construction .and arrangement of parts hereinafter described and claimed.

In the drawings Figure l represents an elevation of ha l? or' a vwheel einbodyin;T the inventgon, the ,ub cap being removed; 2 is a sectional elevation thereof; and 3 is a cross section on the line 3-3, Fig.

Referring;r to the drawings which il ustrate one embodiment or" the invention, the Wheel comprises a hub l, rim 2, and two sets of Wirespokes,w namely, an inner'set 3, and an outer set- 4. The rim may be an;7 ordinary type of rim, such'as the quick detachable, and for either straight side or elencher tires, and is shown as the. latter. The spokes are ordinary n'ire spokes formed of the best quality of drawn steel wire and provided on their outer ends with suitable nipples 5 for securing,r them to the rirn.l and on their inner ends 'ith heads 6 for connectinfr them to the hub.

The hub l, comprises an inner hub member l' which is generally' cylindrical in shape and of uniform diameter from end to' end.

it has tu'o or inore transverse proiided with .apertures throulfii the axle i) projects. A 'key lll .fixes axle to the hull and it is heid thereon by a nut ll screwed on the threaded und ot' the axle.

rl`he shape ot' the hul) depends upon whether the wheel is a from wheel or a irai' or driving wheel. in the latter case the inner end ot the inner hub mouiller mar be provided with a flange lil to 'which illy brake druin ll is rigidi)v secured.

The outer end oi the inner humember is externally"threadial to receina damping nut lll and a cover or dust call li. which alsoy acts a lock nut ior the clamping nut lo.

rihe inner headed ends ot' the splikes il aud l are secured 'to an outer hub ineniber lh. nhieh isvtubular and whose inner diameter issoineu'hat greater than the external dialneter of the in'ner hub niianber. T to provide a clearance space therebetween. The inner hub ineinber provided ou its outer .surtace with a plurality (three being' shou'ul ol5 driving,v clutch jaws or members 1), 'which extend longitudinally oi' the hulz, and each ci' which lies between a pair of cooperating driving elutch "us or membra-s zu proiei-tl inwardly l oni the outer hub ineiulaaz The driving jaws Alil have a fairly close lit between the driving jaws 20, and hoth sets of jay-fs have substantially radial side *faces n: so that the inner hub member positively drives the outer hub i'aeniber in either dirigo tion withoutlooseness or play and without uedging'or eannning action. ,The outer hub member is rigidly secured to the inner hub member and is centralized, with respect thereto .by the clamping nut lo. its shown, the outer hub rneinber is provided on its cpposite ends With beveled or inclined clamping faces 2l, one of which cooperates with a similarly beveled clamping face or abutnient- 22 on the inner hub ineinber, and the other with a like clamping tace 23 on the inner portion of the clamping nut lli. lVhen the clamping nut 1G is screwed up tight the inner end ot the outer hub member At'orced up against the clamping face or abutment Q2 and also wedges aga-,inst the clamping face of the clamping' nut 18 and is thereby rigidly held in place, The wedgingaetion of the clamp compresses the outer hub member inwardly and acts in the saine general line lill as the spokes. Consequently, the clamping the spokes on the hub. Moreover, the oppol site end portions of the outer hub are covered and are reinforced by the clamping nut and the abutment 22 and the spokes areattached close to the ends of the hub, thereby minimizing the liability of the spokes tearing out a portion of the hub when under unusual' strain.

In the foi-m shown, the rim 2 is in a plane near the inner end of the hub, so that the outer spokes 4 are somewhat longer than the spokes 3. The two rows of Aspokesv cross, as

shown at 30, and ltheyfare threaddip in the manner shown in Fig-Nl', each `spoke being substantially tangential to' the hub ywhere secured thereto.

To remove the Wheel from the hub the dustxcap 17 is removed, thereby releasing the clamping'nut 16. The latter is then unscrewed jffom the inner hub member, when the outer hub `member carryingthe spokesv l andriiii can be readily slid endwise from the hub. The clearance space between the inner and outer hub members prevents them trom a( rusting fast, so that the wheels do' not have to be forced oil" from the axles. Moreover,

the inclined clamping faces 21, 22 and 23 form a hermetical seal which absolutely prevents the entrance of dirt, dust, water or moisture to the space between the inner and outer hub members, thereby preventing rust and corrosion.'y

One important. feature of the invention is the fact that the hub members are both of practically uniform diameter from end .to end, and this, diameter can be made large enough so that the spokes' are substantially. tangentialvto both ends of the hub where they ai'esecured thereto. The driving between the outer hub member and rim in each direction is therefore done by'tension in half of both the front and rear row of spokes and not through vonly half of ther rear row of spokes, as is the case'wh'en the hub is conical with the hub portion considerably smaller than the rear portion thereof.

Vith arrangements such as just referred to the spokes of the outer row are practically radial, due to the small size of the hub where they are secured, and therefore they do not take their share of the load. The jaw clutch between the inner and outer hub members, in connection with the clamping eflect of the nut 16 makes the two hub members practically integral 'with each other, so that they do -not tend to Work loose or wear, as is the case kwhen the driving is done vthrough pins and the like.

n IVhat I claim is: e A vehiclewheel, comprising dinner and outer hub members of dilierent'iameterswith a space therebetween, the vinner hub member having a beveled portion surround ing the. outer hub member and closing said bers having substantially radial side faces. In testimony whereof, I have hereunto set my hand. l
